Temperature T/K: A, B, C, D, E – 293.15, -42.9305, 1215, 8.3707, -0.009593, 0. Henry’s coefficient ENH3: 385.0037232 Kpa. *Calculation formula: lnE = A + B/T + C lnT + DT + E/T2 (Aspen). I want to use the formula lnE = A + B/T + C lnT + DT + E/T2 to calculate the value of E; however, there are two databases available in Aspen, and when these values are used in the formula, the results obtained differ significantly. And it does not match the data found in the literature. What is the reason for this? ?
